in the jQuery JCR explorer I iterate over the properties of a resource making use of org.apache.sling.api.resource.PersistableValueMap. I.e. var properties = resource.adaptTo(Packages.org.apache.sling.api.resource.PersistableValueMap);
I then try to "cast" the property to javax.jcr.Property, var property = properties.get( id, Packages.javax.jcr.Property ); Now when I browse through /jcr:system/jcr:nodeTypes (e.g./jcr:system/jcr:nodeTypes/nt:folder) the property jcr:mixinTypes fails to cast. In these cases I fall back to the string representation of the property. In case of /jcr:system/jcr:nodeTypes/nt:folder I get something like: [Ljava.lang.Object;@dbd726 BUT I would expect jcr:mixinTypes to be a multivalued Name property? Hence it should cast properly to Property. Also noticeable: I have no problems with the jcr:supertypes property, which is also a multivalued Name property.
